Block A with mass mA :91 kg, and block B with mass m3 :5 .5 kg, are suspended from opposite ends of the rope, as shown. (This contraption is known as an Atwood's machine.) Consider the motion of the blocks after they are released from rest. Let a be the magnitude of their acceleration, and let FT be the tension in the rope. Let upward be the positive y direction for block B, and let dovmward be the positive y direction for block A. Tran ,Theresa ttran55@mail.sfsu.edu @theexpertta.com tracking id: 6C65-7EA041B9BD-32189.
